Therefore I am 99% sure that the EEPROM on the original control boards also ages (from heat) and the software finally becomes corrupted. Since it is easy to burn an 8 pin EEPROM, I would recommend that someone do just that while your control board is still working.
You could test this theory by dumping the EEPROM on your new board and replacing/flashing the EEPROM on your old board.
